Most of the QLQ-NMIBC24 scales had low correlations (< 0.40) with the EORTC QLQ-C30 scales ( Table 5 ), indicating that the scales of this module are not conceptually overlapping in contents with the QLQ-C30. Exception was malaise scale, which showed correlations > 0.40 with most scales in the QLQ-NMIBC24 and all scales in the QLQ-C30. The urinary symp- Table 6 shows change in six scale scores and five single items before and after treatment. A significant improvement was noted in the urinary symptom scale (24.9 to 21.0 between visits 1 and 2, p=0.051, and 21.0 to 18.2 between visits 2 and 3, p=0.049). Future worries significantly declined between visits 1 and 2 (p=0.001), and the risk of contaminating a partner significantly decreased between visits 2 and 3 (p=0.026). In addition, malaise symptoms showed an improving tendency between visits 1 and 2 (p=0.070), while sexual function showed a decreasing tendency between visits 1 and 2 (p=0.068). In contrast, no difference was observed among visits in the other two scales (bloating and flatulence, male sexual problem) and five single items (intravesical treatment, sexual intimacy, sexual enjoyment, and female sexual problem).
